FISHING-TOOL.

Lacasse.

Application filed December 11, 1919.

To all 'w hom t may concern Be it known that I, HENRY Comune, a citizenof the United States, and a resident of Rose Hill, in the county ofBabaslra and State of Iowa, have invented certain new and usefulImprovements in Fishing-Tools, of which the following is aspecification.

My invention relates to grapples and has reference more particularly totools for fishing dull bits and other implements from wells. l

An object of the present invention is to provide an improved device ofthe character which, upon being lowered into a well or other boring, isadapted to engage and hold the object whereby the same may be removed.

Another object is to so arrange the grappling tongsA and the jawsthereof that a variety of different objects may be readily removed froma boring.

With these and other objects in view the invention consists in certainnovel features of construction and arrangement of parts as will behereinafter set forth and pointed out in the claims, reference being hadto the accompanying drawing, in which- Figure l is a front elevationshowing one form of my invention as in use;

Fig. 2 is an elevation of the device with the front or face plateremoved;

Fig. 3 is a side elevation of the device;

Fig. l is a vertical section taken as on line 4 4 of Fig. l;

Fig. 5 is a front elevation of a modified form of the device as in use;

Fig. 6 is a similar view enlarged and showing the gripping levers setfor action;

Fig. 7 is a side view of the modified form; and

F ig. 8 is a vertical longitudinal section of the same.

Fig. 9 is a vertical longitudinal section taken on aline 9 9 of Fig. 7.

Referring in detail to the drawings and more particularly to Figs. l, 2,8, and 4l it will be noted that I provide a body or stock portioncomprising a face plate A and a baclr plate B spaced apart at the Aupperend by a spacer block C through which the bolts D pass, these bolts alsopassing through the face and back plates and through the stock hangerstraps E E provided with the elongated slots e at their upper ends; nutsd Specification of Letters Patent.

are screwed on the ends of the bolts D and against the said straps, thussecuring the face and back plates and the hanger straps E E together.

Between the face and bach plates a pair of levers F are disposed withtheir lower ends G projecting 1nelow said face and back plates, saidlevers having'the overlapped ears H with central perforations I throughwhich the fulcrum member J passes, said fulcrum being a bolt which alsopasses through the elongated slots a and Z) in the face and bacl;plates, respectively.

The upper ends of the levers are pivotally secured to one end of linksK, the other ends of said links extending on opposite sides of theclevis L in overlapped relation and between said clevis and the slottedhanger straps E l@ and there held by the bolt M and the nut m.

The crossing portions or ears H of the levers are cut out or recessedone-half their thickness so that the space between the face and backplates is the same as the thickness of the upper arms F of the levers.

T he lower ends of Vthe face and bach plates are provided with integralsemi-circular flanges A and B tothe lower face of which are heldsemi-circular extensions A2 and B2 by means of bolts A3 and n3 eXtending from the flanges All and B1 through the open ended slots A4 andB4 in said extensions. rfhese extensions may be moved outwardly and heldto accommodate the tool to the diameter of the boring in which the toolis working.

The lower ends of the levers are provided with parallel obliquely setribs il or knurls on their opposite faces and to such faces arepivotally secured the curved jaws O 0 having corresponding parallel ribsor linurls by which the jaws can be adjusted to practically any angularposition and held there by the bolts P passing through the lower ends ofthe levers and the said jaws.

The opposite side edges of the face and back plates near their upperends are provided with the triangular shaped notches (d and @l intowhich project rigid studs or pins Q? and Q3 from the opposite faces ofthe upper arms F of the levers and in which notches the studs or pinshave lateral play, their inward movement being controlled and limited bystops which consist of a flat plate Q4 having open end elongated slotstherethrough and which are slidably and rotatably mounted on boltsagainst the front of the face plate adjacent the aforesaid notches whichare reentrant. By moving these stops inwardly or outwardly or swingingthemen their pivot the throw of the levers can be controlled .and hencethe eX- tent of the opening of the jaws at the lower ends alsocontrolled.

A cable or rod is secured to the upper end of the clevis L and by thiscable the tool is lowered into the boring with the jaws G spread apartas in the position shown in Fig. 2, the links li being horizontal andthe bolt connecting them, the clevis and the hanger straps, lying withinthe extreme lower end of the elongated slots of the said hanger straps.l/Fhen the lower end of the stock comes in Contact with the bit orarticle to be fished from the boring, the cable is given an upward jerkor pull whereupon the clevis is pulled upward carrying the bolt M up tothe upper end of the elongated slots causing the links to draw inwardlythe upper ends of the levers and closing the jaws on the article andgrip it between them where it is gripped and held by the serrated orsharp ends of the gripping jaws. rl`he bit and this tool can now belifted out of the boring.

rEhe device just described can be used in a plain boring, or it may beused in a well casing, as indicated in Fig. l.

1n Figs. 5, 6, 7 and 8 a modified form is shown and which comprises astock or body portion consisting of a plate R having at its lower end anintegral horizontal flange r, a reduced portion r at its upper end inwhich reduced portion an elongated slot r2 is made and also provided atits central portion with an elongated slot Adjacent the lower end of thestock a pair of cross levers S S are pivotally mounted and held by aheaded bolt 'l which passes through a bulge or enlargement s on thelever S the head of the bolt being seated in the countersunlr ordepression s2 in said bulge thence through lever S and stool: R and thenut s3 on the bolt binding against the stock and resting on the flange rby which it is prevented from turning off, thus constituting a nut lock.

The levers S and S where they cross are recessed or cut out so that theypresent ay uniform thickness throughout their length.

The upper ends of the levers S and are recessed or cut out on oppositesides st et and in these recesses are pivotally mounted the lower endsof the toggle links U being secured to the upper ends of the levers insaid recessed portions by bolts u and secured at their crossing to thereduced upper end of the stock by the bolt u said bolt u also serving asa means of securing the suspen- :incense sion means of the device, which`consists of a plurality of strap sections V the adjacent endsoverlapping and bolted together after the manner of a folding rule. Thebolt u passesthrough the elongated slot r2 in the upper end of thestock, and the lowermost section V of the suspension means is slidablysecured to the back face of the stock by the bolt 'a2 which passesthrough the elongated slot in the central portion of the stoclr, awasher us being placed on the bolt between the s'toclrand the lowersection of the folding suspension means; the slots r2 and r3 are invertical alinement and a washer u3 is also placed on the bolt u betweenthe stock and the said suspension section, all as plainly seen in Fig.8.

llhe lower or jaw ends W of the levers are curved and are provided withVgripping means which in the present instance consist of hardened pointedscrews X threaded through the jaws from the side edges in an obliquedirection with the points projecting upwardly and inwardly through theinner edges of the jaws. These pointed screws, which, it will benoticed, form teeth, can be adjusted to any degree desired so as to gripa large or a small article or tool which may have become broken ordropped into the bottom of the boring.

In using this form of device for fishing it is lowered into the boringor casing with the parts in the position shown in Fig. 6, the suspensiondevice being folded out and extended to its full length. Upon reachingthe bottom or coming in contact with the tool or article to be fished,the suspending means is given a quick jerk upwardly which causes thecrossed levers to close scissors-like, the bolts al and u2 rising to theupper ends of the elongated slots r2 and r3 and drawing the upper andlower ends of the crossed levers to swing toward each other and thepointed screws X to bite into and grip theV article, as shown in Fig. 6.The entire Vdevice vis then pulled upwardly from the boring or casingand the article released from the gripping jaws.
